The LR8 series is based on modern, highly efficient cellular technology with improved passivation. This structure reduces internal losses and improves module performance under:

• high summer temperatures
• uneven lighting
• partial shading
• morning and evening sun

As a result, the station achieves a more uniform generation schedule throughout the day and stable output throughout the year.

The Longi LR8-66HGD 620W is a bifacial solar panel with a glass-on-glass design. The rear surface generates energy through reflected light, making it particularly effective for:

• ground-mounted solar power plants with gravel or light-colored surfaces
• agrivoltaic systems
• facilities with a high albedo coefficient

This approach allows for increased total solar output without expanding the land area or increasing the number of modules.

Using 620W panels allows for:

• reducing the number of modules per MW of installed capacity
• reducing the volume of metal structures
• optimizing logistics and installation
• simplifying string configurations

For EPC companies, this means faster installation, lower infrastructure costs, and reduced project capital expenditures.

The Longi LR8-66HGD 620W is adapted for use with high-voltage system inverters, allowing for longer strings and optimized cable losses. This is important for large industrial plants, where every percentage point of efficiency impacts the financial model.
